Jacksis
A jacksie is a towel that smells like old socks and poop, usually because someone tried to wipe their jacksis and then forgot to wash it.
My towel is a jacksie because I used it to wipe my jacksis and then left it on the floor.
My brother's towel is a jacksie because he used it to wipe his jacksis and then threw it in the trash.
My dog's towel is a jacksie because he used it to wipe his jacksis and then ate it.
